Chris,
Thanks for notifying us of this. Looks like these repairs are below DWR's requirements for a written 401 and the Buffer
impacts are Exempt. You're good to go from here!

Subject: NCDOT Division 5 Rogers Road (SR 2052) pipe failure in Wake Forest, NC
Reference:
WBS Number: 15005.109201
Rob and Eric,
Heavy rain and stormwater runoff associated with Hurricane Matthew on October 6-8, 2016 resulted in failure of the
existing pipe structure and roadway along Rogers Road. The existing 75 foot ling 48 inch pipe structure conveyed
Sanford Creek (WQC index number: 27-23-5; classification: C; NSW). The Department proposes to replace this failed
pipe with a 75 foot long 12 ft-3 in X 7 ft-3 in aluminum structural place arch with headwalls. The project will result in the
following anticipated impacts:
-35 linear feet Class II rip rap streambank stabilization (permanent impact)
-35 linear feet dewatering (temporary stream impact completely concurrent within limits of rip rap bank stabilization)
-35 linear feet riparian buffer impacts (4,200 sq ft BZ 1 impacts)
-An undetermined amount of Class II rip rap will likely be placed within a large blowhole in the stream below the outlet
of the structure. This rip rap will not extend above the invert of the pipe outlet.
Please advise if you need additional information.
Thanks,
Chris Murray
